The liner PM has a temporary-adhesive face PMa on one side and a non-temporary-adhesive face PMb on the other side of the temporary-adhesive face PMa. The plurality of labels PL temporarily adheres to the temporary-adhesive face PMa at predetermined intervals. On the non-temporary-adhesive face PMb, reference marks M are formed at predetermined intervals. Each reference mark M shows the reference position for a label PL. - Each label PL has a print surface PLa and a sticking surface PLb. The print surface PLa includes a thermosensitive layer that develops a color by heat. On the sticking surface PLb, adhesive is applied.
- The following describes the structure of a printer of the present embodiment.
Fig. 2 is a perspective view of the printer of the present embodiment when the printer cover is at a closed position.Fig. 3 is a perspective view of the printer of the present embodiment when the printer cover is at an open position and the head cover is at a shielding position.Fig. 4 is a perspective view of the printer of the present embodiment when the printer cover is at an open position and the head cover is at a non-shielding position.Fig. 5 is an enlarged perspective view of region I ofFig. 4 . - As shown in
Figs. 2 to 4 , theprinter 1 includes afront panel 2, ahousing 8, aprinter cover 3, atouch panel display 4, acontainer 6, aplaten roller 10, a thermal head 12 (one example of a print head), a first assistingroller 13, a second assistingroller 14, aseparator 15, ahead cover 21, a pair of cover locks 24, and a pair of cover lock holes 25. - The
printer cover 3 includes a cover open button 3a at the front end. - The rear end of the
printer cover 3 is pivotally supported at the rear end of thehousing 8. Theprinter cover 3 can move (i.e., is rotatable) relative to thehousing 8 between the closed position (Fig. 2 ) and the open position (Fig. 3 ) about the rotary shaft RS1. - At the closed position, the
printer cover 3 closes the housing 8 (for example, the interior of thehousing 8 cannot be seen from the outside of the printer 1). At the open position, theprinter cover 3 opens the housing 8 (for example, the interior of thehousing 8 can be seen from the outside of the printer 1). When theprinter cover 3 is at the closed position, theplaten roller 10 and thethermal head 12 are opposed. When theprinter cover 3 rotates from the closed position to the open position, the front end of theprinter cover 3 rotates away from thefront panel 2 and the front end of thehousing 8. When theprinter cover 3 rotates from the open position to the closed position, the front end of theprinter cover 3 rotates toward thefront panel 2 and the front end of thehousing 8. When theprinter cover 3 is at the open position, thethermal head 12 is away from theplaten roller 10. Theprinter cover 3 has a front face. The front face is directed upward (UP) when theprinter cover 3 is at the closed position. The front face is directed rearward (RR) when theprinter cover 3 is at the open position. - The
printer cover 3 has a rear face. The rear face is directed downward (LO) when theprinter cover 3 is at the closed position. The rear face is directed forward (FR) when theprinter cover 3 is at the open position. - Located in the
housing 8 are: thefront panel 2, thecontainer 6, the first assistingroller 13, theplaten roller 10, theseparator 15 and the pair of cover lock holes 25. - The
container 6 is located closer to the rear end of thehousing 8. Thecontainer 6 stores a roll of paper R. As shown inFig. 3 , when theprinter cover 3 is at the open position, thecontainer 6 is accessible from the outside of theprinter 1. Then a user can set a roll of paper R into thecontainer 6. - The
platen roller 10 is located forward (FR) of the first assistingroller 13. Theplaten roller 10 is rotatably supported at thehousing 8. Theplaten roller 10 is connected to a stepping motor (not illustrated). Theplaten roller 10 rotates under the control of the stepping motor so as to feed the print medium P. - The first assisting
roller 13 is located forward (FR) of thecontainer 6. The first assistingroller 13 is rotatably supported at thehousing 8. - The
separator 15 is located forward (FR) of theplaten roller 10. Theseparator 15 is a member (e.g., a separation board) having at least one plane or a member (e.g., a separation pin) having at least one curved surface. When theplaten roller 10 feeds a print medium P forward (FR), theseparator 15 folds back the liner PM of the print medium downward (LO) and rearward (RR) so as to separate the printed label PL from the liner PM. - As shown in
Fig. 2 , alabel ejection port 2a is defined between theprinter cover 3 at the closed position and the housing 8 (i.e., above (UP) the front panel 2). Below (LO) thefront panel 2, aliner ejection port 2b is defined. - The
label ejection port 2a is located forward (FR) of theseparator 15. Thelabel ejection port 2a ejects a label PL separated from the liner PM. - The
liner ejection port 2b is located below (LO) thelabel ejection port 2a. Theliner ejection port 2b ejects the liner PM after a label PL is separated from the liner PM. - As shown in
Fig. 2 , when theprinter cover 3 is at the closed position, thetouch panel display 4 is located at the upper face of theprinter cover 3. Thetouch panel display 4 displays predetermined information. The predetermined information contains information on theprinter 1 and images of operation keys. When a user touches an image of an operation key, the processor (which will be described later) of theprinter 1 receives an instruction corresponding to the operation key. Thetouch panel display 4 is a liquid crystal display having a touch sensor, for example. - As shown in
Figs. 3 to 5 , the cover open button 3a, thethermal head 12, the second assistingroller 14, ahead bracket 20, thehead cover 21, a connector unit 22 (one example of a connector), a pair ofgears 23, and the pair of cover locks 24 are attached to theprinter cover 3. When theprinter cover 3 is at the closed position, thethermal head 12, the second assistingroller 14, thehead bracket 20, thehead cover 21, theconnector unit 22, and the pair ofgears 23 are located on the lower face of theprinter cover 3. - As shown in
Figs. 3 and4 , thehead cover 21 is pivotally supported at theprinter cover 3. The head cover 21 can move (i.e., rotate) relative to theprinter cover 3 between a shielding position (one example of a first position) ofFig. 3 and a non-shielding position (one example of a second position) ofFig. 4 about the rotary shaft RS2. The rotary shaft RS2 is parallel to the rotary shaft RS1. - The head cover 21 at the shielding position shields a part of the
thermal head 12. In this case, a part of thethermal head 12 and the connector unit 22 (seeFig. 4 ) are covered by thehead cover 21, and therefore, they cannot be seen from the outside of theprinter 1. - The head cover 21 at the non-shielding position opens the
connector unit 22. Specifically, a space is defined between thehead cover 21 at the non-shielding position and theprinter cover 3. Theconnector unit 22 is exposed through this space. Theconnector unit 22 has a connecting terminal, and the connecting terminal is directed upward (UP). In this case, thethermal head 12 and theconnector unit 22 can be seen from the outside of theprinter 1. - The second assisting
roller 14 is rotatably supported at theprinter cover 3. The second assistingroller 14 is located at a center of thehead cover 21 in the width direction (LH-RH direction). The second assistingroller 14 assists the feeding of the print medium P by being rotated in response to the rotation of the first assistingroller 13. - When the
printer cover 3 is at the closed position as shown inFig. 2 , the pair of cover locks 24 inFig. 3 is inserted into the pair of cover lock holes 25. This fixes theprinter cover 3 at the closed position. When the user presses the cover open button 3a, the fixing by the cover locks 24 is cancelled. As a result, theprinter cover 3 can rotate from the closed position to the open position (Fig. 3 ). - As shown in
Fig. 5 , thehead bracket 20 includes a pair ofprojections 20a, a pair ofprotrusions 20b and ahead bracket body 20d. - The pair of
projections 20a protrudes forward (FR) from thehead bracket body 20d. - The
head cover 21 includes a pair ofengagement parts 21a and a pair ofgears 21b. - The pair of
engagement parts 21a is located at lateral ends of thehead cover 21. The pair ofengagement parts 21a engages with the pair ofprotrusions 20b, whereby thehead cover 21 can be locked at the shielding position (Fig. 3 ). - When a user rotates the
head cover 21, the engagement of the pair ofengagement parts 21a with the pair ofprotrusions 20b is cancelled. - As shown in
Fig. 5 , the pair ofgears 23 engages with a pair ofengagement holes 22f and the pair ofgears 21b. Such engagement via the pair ofgears 23 converts the rotary motion of thehead cover 21 into the motion of theconnector unit 22 in the up-down direction (UP-LO direction). - That is, a gear mechanism is made up of the pair of
gears 21b and the pair ofgears 23, and this gear mechanism is a moving mechanism to join with theconnector unit 22 and thehead cover 21. As thehead cover 21 moves, this moving mechanism moves the connector unit 22 (e.g., slides theconnector unit 22 in the up-down direction (UP-LO direction)) for attachment and detachment of thethermal head 12 and theconnector unit 22. - The
thermal head 12 is attachable and detachable with respect to theconnector unit 22. - The
connector unit 22 is configured to connect thethermal head 12 to a control board (not illustrated). - (3) Attachment and detachment of thermal head and connector unit. The following describes attachment and detachment of the thermal head and the connector unit of the present embodiment.
Figs. 6 to 8 explain how to attach and detach the thermal head and the connector unit of the present embodiment. -
Figs. 6 to 8 show the cross section of a major part of theprinter cover 3 at the open position (Fig. 3 ). - As shown in
Fig. 6 , when theprinter cover 3 is at the open position and thehead cover 21 is at the non-shielding position, thethermal head 12 is open. At this time, thethermal head 12 can be seen from the forward (FR) of theprinter cover 3. - When the user rotates the
head cover 21 clockwise (Fig. 6 ) about the rotary shaft RS2, thegears 23 rotate counterclockwise (Fig. 6 ) about the rotary shaft RS3. Thegears 23 rotated counterclockwise push theengagement holes 22f upward (UP) so as to move theconnector unit 22 upward (UP) (i.e., in the direction closer to thethermal head 12 held by the head bracket 20). - As a result, as shown in
Fig. 7 , thehead cover 21 moves to the shielding position. This connects thethermal head 12 to theconnector unit 22. - Next, when the user rotates the
printer cover 3 counterclockwise (Fig. 7 ) about the rotary shaft RS1, theprinter cover 3 moves to the closed position (Fig. 2 ). - When the user rotates the
head cover 21 at the shielding position (Fig. 7 ) counterclockwise (Fig. 8 ) about the rotary shaft RS2, thegears 23 rotate clockwise (Fig. 8 ) about the rotary shaft RS3. Thegears 23 rotated clockwise push theengagement holes 22f downward (LO) so as to move theconnector unit 22 downward (LO) (i.e., in the direction away from thethermal head 12 held by the head bracket 20). - As a result, as shown in
Fig. 6 , thehead cover 21 moves to the non-shielding position. This detaches thethermal head 12 from theconnector unit 22. - The following describes the functional block of a printer of the present embodiment.
Fig. 10 is a functional block diagram of the printer of the present embodiment. - As shown in
Fig. 10 , the printer includes acontrol board 100, and the control includes amemory 101, a processor 102 (one example of a controller), an input/output interface 103, and acommunication interface 104. - The
memory 101 stores programs and data. Thememory 101 may be the combination of a Read Only Memory (ROM), a Random Access Memory (RAM), and a storage (e.g., a flash memory or a hard disk drive), for example. The programs contain firmware and software. The firmware is a program to control the hardware of theprinter 1. The software is a program to implement the functions of theprinter 1. The data includes control data referred to by the firmware and processing data referred to by the software. - The
processor 102 starts a program stored in thememory 101 and refers to data stored in thememory 101 so as to implement the functions of theprinter 1. Specifically, theprocessor 102 implements a communication control function, a display control function, an instruction receiving function, a print control function and a power control function. Theprocessor 102 may be a Central Processing Unit (CPU ), for example. - The
processor 102 implementing a communication control function controls a communication between theprinter 1 and a device connected to the printer 1 (e.g., a smartphone, a tablet, a personal computer, or a server) via thecommunication interface 104. The communication control function connects theprinter 1 to a network (e.g., the internet, intranet, local area network, or a combination of them). - The
processor 102 implementing a display control function displays information to be displayed on thetouch panel display 4 via the input/output interface 103. - When the user touches one of the operation key images displayed on the
touch panel display 4, theprocessor 102 implementing an instruction receiving function receives an instruction corresponding to the operation key image touched by the user via the input/output interface 103. - The
processor 102 implementing a print control function controls the driving of the stepping motor (i.e., the rotation of the platen roller 10) and heat generation of thethermal head 12. - The input/
output interface 103 receives an instruction from a user through an input device (e.g., the touch panel display 4) of theprinter 1 and outputs information to an output device (e.g., the touch panel display 4) of theprinter 1. - The
communication interface 104 controls a communication between theprinter 1 and a device connected to theprinter 1. - The
processor 102 implementing a power control function controls the power supply to thethermal head 12 via theconnector unit 22. - The following describes a print control function of the present embodiment.
Fig. 9 schematically shows the feed path of the present embodiment. - As shown in
Fig. 9 , the feed path of the print medium P is a path between thecontainer 6 and theseparator 15. The feed path of the print medium P extends through the first assistingroller 13, the second assistingroller 14, thethermal head 12 and theplaten roller 10. The feed path of the labels PL is a path between theseparator 15 and thelabel ejection port 2a. The feed path of the liner PM is a path between theseparator 15 and theliner ejection port 2b. The feed path of the liner PM extends through afirst nip roller 16 and asecond nip roller 17. - The
container 6 stores a roll of paper R. - The first assisting
roller 13 and the second assistingroller 14 are located downstream of thecontainer 6 in the feeding direction. The first assistingroller 13 is located under (LO) the feed path. The second assistingroller 14 is located above (UP) the feed path. That is, when theprinter cover 3 is at the closed position (Fig. 2 ), the first assistingroller 13 and the second assistingroller 14 are opposed. The first assistingroller 13 is connected to a stepping motor. The first assistingroller 13 rotates under the control of the stepping motor. The second assistingroller 14 rotates following the rotation of the first assistingroller 13. The first assistingroller 13 and the second assistingroller 14 rotate while sandwiching the print medium P therebetween so as to assist the feeding of the print medium P. - The
platen roller 10 and thethermal head 12 are located downstream of the first assistingroller 13 and the second assistingroller 14 in the feeding direction. Theplaten roller 10 is located below (LO) the feed path. - The
thermal head 12 is located above (UP) the feed path. That is, when theprinter cover 3 is at the closed position (Fig. 2 ), theplaten roller 10 and thethermal head 12 are opposed. - The
separator 15 is located downstream of theplaten roller 10 and thethermal head 12 in the feeding direction. The upper face and the front face of theseparator 15 define a sharp angle. - The
first nip roller 16 and thesecond nip roller 17 are located downstream of theseparator 15 in the feeding direction. Thefirst nip roller 16 and thesecond nip roller 17 are opposed. Thefirst nip roller 16 rotates following the rotation of thesecond nip roller 17. Thesecond nip roller 17 is connected to a stepping motor. Thesecond nip roller 17 rotates under the control of the stepping motor. Thefirst nip roller 16 and thesecond nip roller 17 rotate while sandwiching the liner PM therebetween so as to feed the liner PM from theseparator 15 to theliner ejection port 2b. - As the
platen roller 10 rotates forward (counterclockwise inFig. 6 ), a belt-like print medium P (the combination of labels PL and liner PM) is extracted from thecontainer 6 to the downstream of thecontainer 6 in the feeding direction. The lower face of the extracted print medium P is the non-temporary-adhesive face PMb of the liner PM. The upper face of the extracted print medium P is the print surface PLa. - As the
platen roller 10 rotates forward, the first assistingroller 13 rotates counterclockwise inFig. 6 while having a contact with the non-temporary-adhesive face PMb. At the same time, the second assistingroller 14 rotates clockwise inFig. 6 while having a contact with the print surface PLa. - The print medium P extracted from the
container 6 passes through between theplaten roller 10 and thethermal head 12 while having a contact with the second assistingroller 14 at the print surface PLa (i.e., the upper face of the print medium P) and having a contact with the first assistingroller 13 at the non-temporary-adhesive face PMb (i.e., the lower face of the print medium P). - The
processor 102 receives print data corresponding to information (hereinafter called "print information") to be printed on the print surface PLa in response to a user's instruction. Theprocessor 102 controls the heater elements to generate heat in accordance with the print data. - When the print medium P passes through between the
thermal head 12 and theplaten roller 10, the heater elements generating heat are pressed against the print surface PLa. Due to the heat of the heater elements, the thermosensitive layer at the print surface PLa develops a color. As a result, print information is printed on the print surface PLa. - The label PL is fed from the front end of the
separator 15 to thelabel ejection port 2a. The liner PM is folded back downward (LO) and rearward (RR) along the front face of theseparator 15, and then is fed toward theliner ejection port 2b. That is, theseparator 15 folds back the liner PM at a sharp angle relative to the label PL. As a result, theseparator 15 separates the label PL from the liner PM. - The
label ejection port 2a ejects the label PL separated from the liner PM. The liner PM after the label PL is separated (i.e., the liner PM passing through the front end of the separator 15) passes through between thefirst nip roller 16 and thesecond nip roller 17, and then is ejected from theliner ejection port 2b. - The following describes a power control function of the present embodiment.
- The
processor 102 of the present embodiment is configured to stop power supply to the print head via theconnector unit 22 when theplaten roller 10 and thethermal head 12 are separated. The following describes examples of the power control function when theprocessor 102 stops the power supply to thethermal head 12. - The following describes a first example of the power control function of the present embodiment.
- As shown in
Fig. 8 , when thethermal head 12 is detached from theconnector unit 22 while leaving theprinter 1 ON, thethermal head 12 is separated from theplaten roller 10. In this case, theprocessor 102 stops the power supply to thethermal head 12 via theconnector unit 22. - Specifically, the
processor 102 is configured to detect whether thethermal head 12 and theconnector unit 22 are connected or not. When theprocessor 102 detects thethermal head 12 not connecting to the connector unit 22 (i.e., separating of theplaten roller 10 from the thermal head 12), theprocessor 102 stops the power supply to thethermal head 12. - After stopping the power supply, a user replaces the
thermal head 12. During the replacement, the user may connect a connector 12b of a newthermal head 12 to anincorrect terminal 22a (i.e., incorrect connection may occur). In case of such an incorrect connection, no current flows through thethermal head 12 because power supply to thethermal head 12 is stopped. This can prevent short circuit of thethermal head 12 during the replacement of thethermal head 12. - When the
thermal head 12 is connected to theconnector unit 22 as shown inFig. 7 , theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22 after the connection of thethermal head 12 to theconnector unit 22. That is, the user can restart the power supply to thethermal head 12 simply by moving thehead cover 21 to the shielding position. Therefore, any instruction to restart the power supply (e.g., an instruction using an operation key image) is not required. This can reduce the user's labor to replace thethermal head 12. - The following describes a second example of the power control function of the present embodiment. In this second example, the
processor 102 stops the power supply to the print head via theconnector unit 22 when theplaten roller 10 and thethermal head 12 are separated. - When the
printer cover 3 is at the closed position as shown inFig. 2 , the user presses the cover open button 3a to cancel the fixing by the cover locks 24. Then when the user rotates theprinter cover 3 toward the open position (Fig. 3 ), thethermal head 12 separates from theplaten roller 10. In this case, theprocessor 102 stops the power supply to thethermal head 12 via theconnector unit 22, at a time in a period of time during which theprinter cover 3 starts moving from the closed position until reaches the open position (i.e., a period of time during which thethermal head 12 is separated from the platen roller 10). - In one example, the
printer 1 includes a lock sensor (not illustrated), and this lock sensor detects whether theprinter cover 3 is fixed or not by the cover locks 24. When the lock sensor detects the cancellation of the fixing of the printer cover 3 (i.e., separation of theplaten roller 10 from the thermal head 12), theprocessor 102 stops the power supply to thethermal head 12. - In another example, the
printer 1 includes a cover sensor to detect the position of theprinter cover 3. When the cover sensor detects theprinter cover 3 being located between the closed position and the open position (i.e., theplaten roller 10 separates from the thermal head 12), theprocessor 102 stops the power supply to thethermal head 12. - In case of an incorrect connection, no current flows through the
thermal head 12 after the power supply stops. This can prevent short circuit of thethermal head 12 during the replacement of thethermal head 12. - When the user rotates the
printer cover 3 from the open position (Fig. 3 ) to the closed position (Fig. 2 ), theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. Specifically, when the cover sensor detects theprinter cover 3 being located at the closed position (i.e., theplaten roller 10 does not separate from the thermal head 12), theprocessor 102 restarts the power supply to thethermal head 12. That is, the user can restart the power supply to thethermal head 12 simply by placing theprinter cover 3 at the closed position. Therefore, no instruction to restart the power supply is required. This can reduce the user's labor to replace thethermal head 12. - As stated above, the
processor 102 of the present embodiment is configured to stop the power supply to thethermal head 12 via theconnector unit 22 when theplaten roller 10 and thethermal head 12 are separated. In case of an incorrect connection during the attachment of thethermal head 12 to theconnector unit 22, no current flows through thethermal head 12. This can prevent short circuit of thethermal head 12 during the replacement of thethermal head 12. - The following describes modified examples of the present embodiment.
- The following describes Modified Example 1. Modified Example 1 shows an example of controlling the power supply based on whether the
thermal head 12 is fixed or not. - The
printer 1 of Modified Example 1 includes a head lock member (not illustrated) and a head lock sensor (not illustrated). - The
thermal head 12 of Modified Example 1 can move while keeping a connection to theconnector unit 22. The user is allowed to move thethermal head 12 connected to theconnector unit 22, and so the user can easily see such athermal head 12 connected to theconnector unit 22. Therefore, the user can easily attach and detach thethermal head 12 and theconnector unit 22. - The head lock member is configured to fix the position of the thermal head 12 (
Fig. 7 ) connected to theconnector unit 22. The head lock member may be a lever, for example. - The head lock sensor detects whether the fixing by the head lock member is cancelled or not.
- When the fixing by the head lock member is cancelled, the
processor 102 stops the power supply to thethermal head 12 via theconnector unit 22. Specifically, when the head lock sensor detects the cancellation of the fixing by the head lock member, theprocessor 102 stops the power supply to thethermal head 12 via theconnector unit 22. In case of an incorrect connection, no current flows through thethermal head 12 after the power supply stops. This can prevent short circuit of thethermal head 12 due to incorrect connection. - When the head lock member fixes the position of the
thermal head 12 connected to theconnector unit 22, theprocessor 102 restarts the power supply to thethermal head 1 2 via theconnector unit 22. Specifically, when the head lock sensor detects the fixing of thethermal head 12 by the head lock member, theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. That is, the user can restart the power supply to thethermal head 12 simply by fixing thethermal head 12 connected to theconnector unit 22 using the head lock member. Therefore, no instruction to restart the power supply is required. This can reduce the user's labor to replace thethermal head 12. - The following describes Modified Example 2. Modified Example 2 shows an example of controlling the power supply to a printer configured to print information using an ink ribbon.
- The print surface PLa in Modified Example 2 does not include a thermosensitive layer.
- Instead, the
printer 1 of Modified Example 2 includes a ribbon cartridge (not illustrated), a ribbon supplier (not illustrated), a print head (not illustrated) and a ribbon sensor (not illustrated). - The ribbon cartridge stores an ink ribbon. The ink ribbon includes a paper core and a ribbon wound around the paper core (i.e., a roll of ribbon).
- The ribbon cartridge has a ribbon shaft (one example of a ribbon holding part). The ribbon shaft holds the paper core. The ribbon shaft can move between a holding position (one example of a first position) and a not-holding position (one example of a second position). When the ribbon shaft is at the holding position, the ribbon cartridge holds the ink ribbon. In this case, the ribbon supplier can supply the ink ribbon. When the ribbon shaft is at the not-holding position, a user can replace the ink ribbon.
- The ribbon sensor detects the position of the ribbon shaft.
- The ribbon supplier is configured to supply the ink ribbon held by the ribbon shaft to the
thermal head 12. Theplaten roller 10 and thethermal head 12 sandwich the print medium P fed by theplaten roller 10 and the ink ribbon supplied by the ribbon supplier therebetween. - When the ribbon shaft is separated from the holding position, the
processor 102 stops the power supply to thethermal head 12 via theconnector unit 22. - Specifically, when the ribbon sensor detects the separation of the ribbon shaft from the holding position (i.e., separation of the
platen roller 10 from the thermal head 12), theprocessor 102 stops the power supply to thethermal head 12 via theconnector unit 22. In case of an incorrect connection, no current flows through thethermal head 12 after the power supply stops. This can prevent short circuit of thethermal head 12 due to incorrect connection. - When the ribbon shaft moves to the holding position, the
processor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. Specifically, when the ribbon sensor detects the ribbon shaft located at the holding position (i.e., theplaten roller 10 does not separate from the thermal head 12), theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. That is, the user can restart the power supply simply by moving the ribbon shaft to the holding position. Therefore, no instruction to restart the power supply is required. This can reduce the user's labor to replace thethermal head 12. - The following describes Modified Example 3. In Modified Example 3, once the power supply to the
thermal head 12 via theconnector unit 22 stops, the power supply restarts after detecting correct connection of thethermal head 12 and theconnector unit 22. - The
connector unit 22 of Modified Example 3 includes a check circuit. The check circuit includes a switch. The switch is configured to switch between ON and OFF based on whether thethermal head 12 and theconnector unit 22 are correctly connected or not. - The
processor 102 is configured to flow predetermined check current through the check circuit and detect a predetermined voltage across the check circuit. - The switch turns ON when the
thermal head 12 and theconnector unit 22 are correctly connected. When the switch turns ON, check current flows through the check circuit. When the check current flows through the check circuit, theprocessor 102 detects a predetermined voltage across the check circuit. Theprocessor 102 detects the correct connection between thethermal head 12 and theconnector unit 22 by detecting the predetermined voltage across the check circuit. In this case, theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. - In case of incorrect connection between the
thermal head 12 and theconnector unit 22, the switch turns OFF. When the switch turns OFF, no current flows through the check circuit. Therefore, theprocessor 102 does not detect a predetermined voltage across the check circuit. In this case, theprocessor 102 does not restart the power supply to thethermal head 12 via theconnector unit 22. - As described above, in Modified Example 3, the
processor 102 detects correct connection between thethermal head 12 and theconnector unit 22 based on the detection result of voltage across the check circuit. When detecting the correct connection between thethermal head 12 and theconnector unit 22, theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. This can prevent short circuit of the 12 more reliably. - The following describes Modified Example 4. In Modified Example 4, a user moves the
thermal head 12 instead of theconnector unit 22 to attach and detach thethermal head 12 and theconnector unit 22. - In one example, a
head bracket 20 ofFig. 5 has a pair of engagement holes. Thehead bracket 20 holds thethermal head 12. The pair ofgears 23 engages with the pair of engagement holes of thehead bracket 20 and not with the pair ofengagement holes 22f. That is, thehead cover 21 joins with thethermal head 12 held by thehead bracket 20 via the pair ofgears 23. When a user rotates thehead cover 21 clockwise around the rotary shaft RS2 ofFig. 9 , thehead bracket 20 moves downward (LO) (i.e., in the direction toward the connector unit 22) with the rotation of thegears 23 while holding thethermal head 12. - As stated above, in Modified Example 4, the moving mechanism moves the
head bracket 20 with the motion of thehead cover 21. Attachment or detachment of thethermal head 12 and theconnector unit 22 occurs with the motion of the head bracket. - The following describes Modified Example 5. In Modified Example 5, power supply to the
thermal head 12 is controlled based on whether a head unit including thethermal head 12 is separated or not from theplaten roller 10. - The following describes the structure of a printer of Modified Example 5.
Fig. 11 schematically shows the internal structure of a printer according to modified example 5.Fig. 12 is an enlarged view of the print unit ofFig. 11 . - As shown in
Fig. 11 , the printer of Modified Example 5 includes aprint unit 30. Theprint unit 30 is located forward (FR) of thecontainer 6. - As shown in
Fig. 12A , theprint unit 30 includes ahead unit 31, afeed unit 32, and ashaft 33. - The
feed unit 32 includes theshaft 33 and theplaten roller 10. - The
head unit 31 has arear end 31r, and the rear end is pivotally supported at theshaft 33. Thehead unit 31 is rotatable relative to thefeed unit 32 about theshaft 33. Thehead unit 31 has afront end 31f, and the front end is a free end. Therear end 31r is a fixed end. That is, thehead unit 31 can be open or closed relative to thefeed unit 32. -
Fig. 12A shows thehead unit 31 at the closed position that closes thefeed unit 32. At the closed position, thefront end 31f is located above (UP) theplaten roller 10. That is, thehead unit 31 covers the region above (UP) thefeed unit 32. In this way, thehead unit 31 at the closed position closes thefeed unit 32. -
Fig. 12B shows thehead unit 31 at the open position that opens thefeed unit 32. At the open position, thefront end 31f is separated from theplaten roller 10. That is, thehead unit 31 opens the region above (UP) thefeed unit 32. In this way, thehead unit 31 at the open position opens thefeed unit 32. - The
head unit 31 includes thethermal head 12 and theengagement part 34. - The
thermal head 12 is located on the lower face of thehead unit 31. As shown inFig. 12B , when thehead unit 31 is at the open position, thethermal head 12 is separated from theplaten roller 10. - The
engagement part 34 engages with the shaft (not illustrated) of theplaten roller 10. When thehead unit 31 rotates so that thefront end 31f inFig. 12B moves forward (FR), theengagement part 34 engages with the shaft of theplaten roller 10. This results in thehead unit 31 located at the closed position as shown inFig. 12A . - A sensor (not illustrated) is disposed along the shaft of the
platen roller 10. The sensor generates an electrical signal indicating "contact" or "non-contact" between the shaft of theplaten roller 10 and theengagement part 34. Such an electrical signal generated by the sensor indicates whether thehead unit 31 is at the closed position or not. - When the electrical signal generated by the sensor indicates "contact", the
processor 102 supplies power to thethermal head 12. That is, when thehead unit 31 is at the closed position, power is supplied to thethermal head 12. - To replace the
thermal head 12, a user is required to cancel the engagement of thehead unit 31 with thefeed unit 32 and rotate thehead unit 31 so that thefront end 3 If moves rearward (RR). - When the
engagement part 34 separates from the shaft of theplaten roller 10, the sensor generates an electrical signal indicating "non-contact" (i.e., separation of theplaten roller 10 and the thermal head 12). In this case, theprocessor 102 stops the power supply to thethermal head 12. That is, when thehead unit 31 separates from the closed position, the power supply to thethermal head 12 stops. - As stated above, in Modified Example 5, the power supply to the
thermal head 12 switches based on whether thefeed unit 32 including theplaten roller 10 and thehead unit 31 including thethermal head 12 separate or not. Particularly when the user moves thehead unit 31 at the closed position to the open position to replace thethermal head 12, the power supply to thethermal head 12 stops. This can prevent short circuit of thethermal head 12 more reliably. - The following describes Modified Example 6. In Modified Example 6, the power supply to the
thermal head 12 is controlled in accordance with the progress of print. - The
processor 102 stops the power supply to thethermal head 12 via theconnector unit 22 when the print ends. - In one example, the
processor 102 stops the power supply after the elapse of a certain period of time from the reception of print data. - In another example, when the user touches one of the operation key images displayed on the
touch panel display 4 to instruct printing on the designated number of labels PL, theprocessor 102 creates print data for printing on the designated number of labels PL via the input/output interface 103. Theprocessor 102 controls to print on the designated number of labels PL in accordance with the print data. When the printing on the designated number of labels PL ends, theprocessor 102 stops the power supply. - When the
thermal head 12 is connected to theprocessor 22 as shown inFig. 7 and when theprocessor 102 receives print data, then theprocessor 102 restarts the power supply to thethermal head 12 via theconnector unit 22. That is, the user can restart the power supply to thethermal head 12 simply by placing thehead cover 21 to the shielding position. Therefore, no instruction to restart the power supply is required. This can reduce the user's labor to replace thethermal head 12. - The following describes other modified examples.
- The above embodiments exemplify the print medium P having the liner PM and the labels PL, and the print medium P is not limited to this. The print medium P may be a label PL without a liner PM, for example.
- That is detailed descriptions on the embodiments of the present invention, and the scope of the present invention is not limited to these embodiments. The above embodiments can be modi fied or changed variously within the scope of the claims.. The above embodiments and modified examples can be combined within the scope of the claims. The scope of the invention is only defined by the appended claims.
